VEHICLE-WHEEL.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application flied July 6, 1914. Serial No. 848,321.

Be it known that I, Gnonon A. Monroo'r, a citizen of the United States,and resident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Vehicle-Wheels, of whichthe following is a specification and which are illustrated in theaccompanying drawings, forming a part thereof.

- The invention relates to that type of vehicle wheels which, whilehaving a solid tread portion, are provided with cushionin'g meansbetween the tread or rim and the hub.

The object of the invention is to provide a'simple, practicable andefficient wheel of this type; and the invention consists in a structuresuch as is hereinafter described, and is illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of the wheel, someportions being broken away; Fig. 2 is a central axial sectional viewthereof; and Fig 3 shows one of the bolts used for locking the tread andhub portions together.

The hub portion of the wheel comprises an annulus 10, preferably ofwood, and

which incloses and carries suitably united anti-friction rollers, as 11,12, as many heing used as may be deemed advisable, which run upon theaxle. The tread portion of the wheel 13 is annular in form, and may beof metal or wood, as may be preferred. A pair of side plates 14, 15, aresecured rigidly to the tread portion or rim 13, and extend inwardly andoverlap and slidingly engage the annulus 10. Theseparts are held insliding engagementby means of bolts 16, 17, shown as four in number,these bolts fitting snugly in apertures in the member 10 and passingloosely through aper tures 18, 19, in the plates 14, 15. apertures areof suflicient size to permit the desired range of movement of the unitedparts. A hub cap 20 may be held in place also by the same bolts.

A tube 21, adapted to be inflated with air through a suitable nipple 22,rests upon an annular channeled seat 23, carried by a' disk 24 extendingradially from the member 10, this tube bearing upon the inner face ofthe tread portion or rim 13. The rollers 11, 12, are mounted upon stubshafts 25, 26, which may be and are shown as screws setting through sideplates 27, 28, secured to and extending inwardly from the mem- These her'10, these screws carrying bushings 29 upon WhlCh the rollers 11, 12,may turn, and nuts 30, 31, being mounted upon the screws at each side ofeach of the rollers to prevent lateral movement thereof.

In order to adapt the wheel for use upon any particular axle, as 32, asleeve 33 may be fitted upon the axle skein 34, its periphery beingprovided with bearing surfaces of uniform diameter for the rollers.

The plates 14, 15, may be apertured in order to reduce the weight, asplainly shown. The tube 21 provides the same cushioning action as issecured in the ordinary pneumatic tire, but is protected from wear andinjury by the solid tread portion 13. It may therefore, be made muchlighter than the casing of a pneumatic tire which constitutes the treadportion of a wheel. Broadly considered, the wheel as described is of theordinary pneumatic tire type, with a solid protecting rim fitted uponthe outer face of the cushioning tube.

' Provision is made for temporarily locking the tread and hub portionsrigidly together should the tube become deflated. This feature consistsin providing the plates .14, 15, and the member 10 with two or moreregistering apertures 35, 36, through which bolts may be passed forsecuring these parts together. When such bolts are applied the wheel is,of course, without cushioning action but will support the vehicle andpermit it to be driven to a suitable place for making repairs.

I claim as my invention- 1. In a wheel of the class described, a

hub member provided between its ends with a circumscribing radialflange, cushion seating members secured to the said flange, a cushionsupported by said seating members, a tread member surrounding 'the saidcushion, side plates secured to the opposite sides of the said treadmember and fitting slidably against the end faces of the said member,the said plates being provided each with a series of openings, boltsfitted through the hub member and projecting at their ends through thesaid openings in the said plates, and a hub cap plate supported by thesaid bolts in spaced relation to one end of the-said hub member andbearing against one face of one of said side plates.

2. In a wheel of the class described, a hub member provided between itsends with a circumscribing radial flange, cushion seating memberssecured to the opposite sides of the said flange at the marginal portionthereof, a pneumatic cushion surrounding and seating upon the saidseating members, a rigid tread member surrounding the said cushion,annular side plates secured at their outer marginal portions to theopposite sides of the said tread member and at their inner portionsfitting slidably against the end faces of the said hub member, the saidplates being provided each with a series of openings, bolts fittedthrough the hub member and projecting at their ends through the saidopenings in the said plates, and a hub cap plate supported by the saidbolts in spaced relation to the outer end of the said hub member andbearing against the outer face of the outer one of the said side plates.
